Table 37: Detector Used as Pushbutton Operational Description The following table applies where:

• pedestrian protection is required to vary depending on which pushbutton is pressed;

• a vehicle detector is to be used as a pedestrian pushbutton for the purpose of making the timed red protection conditional.

When the detector is operated red protection is provided for:

• walk; and

• clearance based on timer.

The table also provides functionality to:

• prevent oscillating detector alarms;

• allow a detector alarm only if the detector has short circuit operation.

ONLY CERTAIN VEHICLE SIGNAL GROUP TABLES CAN TAKE ADVANTAGE OF THIS FUNCTIONALITY.
